Door popping circuit

ah, thanks for your time. Im affraid i cant follow that diagram. As i said, im new to electronics and have never used a relay before, so all the pins mean nothing to me. I dont know the diffrence and what each one does.

All i know is, i want a button on the outside of my car that will only operate when the keyfob has been pressed, and will not work any of the other time.

auex, does this system above work as the keyfob remote only sends a short pulse through to the solenoids.

i do like the idea's, but i just dont understand. Im sorry if this offends, i was just told by a friend that this forum is very helpful when it comes to technical help.

Im just looking for a solution to my problem is all, and i cant understand the above diagram as its just coloured lines to me, id need some helpful explanations with it for a newbie like myself.

its not that i dont want an alarm that has this function, its the fact that in the UK you need a button on the outside of the car.

Simply having the door pop open from a remote is not enough to pass the safety test you have to take each year, so the car wont be legal. If the cops pull you over, they check all the documents and if you dont have the safety certificate then you will lose your license. I hope this explains it a bit better.

So i need a button on the outside, but not one that works when im not at the car otherwise anyone will just press it and be able to jump in.

Because the remote keyfob button only sends a pulse through the system, just having a normal relay is not good enough as it will click over when it pulses, but then click back straight away again. I need something that will click over with the pulse, and then stay there.

that is what i want to do bobk.

Press the remote key fob button which then enables the door popping circuit, allowing me to push a button on the outside of the car to gain entry.

If the remote key fob button has not been pressed, then the button on the outside of the car will do nothing.

Its the help with the relay's i need, as i dont know how to set them up to achive my task. I was under the impression that just a pulse from the remote key fob circuit will go through the relay, click it over, and then once the pulse has passed it will immediately click back over. This will only give me a spilt second to press the button on the outside of the car, which will not be good enough.

I hope this explains things a bit better.

Can anyone look at my resived diagram below, and tell me if it will work. I have incorporated a standard relay and i think this might cure my problem of the timer shutting down the system once i am in the car and driving. Thanks for all your help on this.

hi Powermyster. Sorry if you cant follow my diagrams, i dont know how to draw electrical diagrams properly.

But what you have said above is exactly what my diagram shows! The normal relay comes from the ignition which then bypasses the timer circuit meaning the popping circuit is always open when the igntion is on. If the ignition is off, then the interal buttons still work, but the external buttons only work once the keyfob has been pressed.

I think this is my final design.
